iRobot Roomba j9+ Robot Vacuum - 113-Minute Tested Runtime
Published on 09/22/2026 at 08:32 | Editorial responsibility: Rafael Müller, Editor-in-Chief AD HOC NEWS
iRobot Roomba j9+ robot vacuum moves across carpet and hard floors with a 13.7-inch diameter and a 3.4-inch height. Its camera-based navigation identifies objects such as cords, shoes, socks, and pet waste while the Clean Base automatically empties the dustbin.
Core Specifications And Included Parts
The exact US model is J955020. iRobot lists the robot at 13.7 by 13.7 by 3.4 inches and 8.98 pounds, with a lithium-ion battery and a Clean Base measuring 15.8 by 12.2 by 13.3 inches. The manufacturer specifications also identify the model number and included accessories.
The package includes the Roomba robot vacuum, Clean Base Automatic Dirt Disposal, one extra high-efficiency filter, one extra dirt-disposal bag, and a line cord. The Clean Base bag is rated for up to 60 days of debris, while the robot uses dual multi-surface rubber brushes, an edge-sweeping brush, and three-stage cleaning.
Navigation And Cleaning Results
PrecisionVision navigation uses a front-facing camera to recognize and avoid household obstacles. iRobot also pairs the j9+ with Dirt Detective, which uses cleaning history to prioritize dirtier rooms and adjust suction and cleaning passes.
PCMag tested the Roomba j9+ for 113 minutes before a recharge, compared with 86 minutes for the predecessor Roomba j7+. In the same testing program, the j9+ collected 95.8% of large debris from carpet and 88.4% from hardwood, while small-particle pickup measured 38.5% on carpet and 54.3% on hardwood. These independent test results apply to controlled single-run measurements.
The j9+ is a vacuum-only robot, not the Combo j9+ hybrid. The Combo model adds mopping and launched at $1,399.99, while PCMag listed the standalone j9+ at $899.99. That distinction matters because the j9+ dock does not include the Combo model's water reservoir.
Price And Category Position
The US launch price was $899.99, and PCMag placed the model at the high end of standalone robot vacuums. Best Buy's listing identifies the product as a self-emptying robotic vacuum with a 7-inch cleaning path, a 0.1-gallon bin capacity, and a 7-pound out-of-box product weight. The US retailer listing identifies the Ruby Bronze version.
Against the j7+, the j9+ delivered a tested runtime of 113 minutes versus 86 minutes. Against the Combo j9+, it gives up mopping but uses a smaller, vacuum-focused dock. The result is a premium robot vacuum aimed at homes where obstacle avoidance, room mapping, and automatic emptying matter more than wet cleaning.
Verdict For Vacuum-Only Homes
The Roomba j9+ fits households that want a self-emptying vacuum with camera-based obstacle recognition and app-controlled room cleaning. Its measured 113-minute runtime and 60-day Clean Base capacity support longer cleaning cycles, but the vacuum-only design rules out mopping and its $899.99 launch price places it above basic robot vacuums.
